The Basics of Math-Made Clear

  Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas.These 30 fantastic lectures are designed to provide students with an understanding of arithmetic and to prepare them for Algebra(代数)and beyond.

  The lessons in Basic Math cover every basic aspect of arithmetic.They also look into exponents(指数), the order of operations, and square roots.In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically.

  Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students.The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening.They also help students prepare for college mathematics and overcome their anxiety about this amazing-and completely understandable-field of study.

  By the conclusion of the course, students will have improved their understanding of basic math.They will be able to clear away the mystery(神秘性)of mathematics and face their studies with more confidence than they ever imagined.In addition, they will strengthen their ability to accept new and exciting mathematical challenges.

  Professor H.Siegel, honored by Kentucky Educational Television as “the best math teacher in America,” is a devoted teacher and has a gift for explaining mathematical concepts in ways that make them seem clear and obvious.From the basic concrete ideas to the more abstract problems, he is master in making math lectures learner-friendlier and less scary.

  With a PhD in Mathematics Education from Georgia State University, Dr.Siegel teaches mathematics at Central Arizona College.His courses include various make-up classes and a number of lectures for future primary school teachers.

  If the course fails to provide complete satisfaction to you, you can easily exchange it for any other course that we offer.Or you can get your money back.

Today, bicycles are elegantly simple machines that are common around the world. Many people ride bicycles for recreation, whereas others use them as a means of transportation. The first bicycle was invented in Germany in 1818. Because it was made of wood, it wasn’t very strong nor did it have pedals (脚踏板).Riders moved it by pushing their feet against the ground.

In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, invented a much better bicycle. Macmillan’s machine had iron-covered wheels to keep them from getting worn down. He also used foot-operated levers, similar to pedals, so his bicycle could be ridden at a quick pace. It didn’t look much like the modem bicycle, though, because its back wheel was substantially larger than its front wheel. Although Macmillan’s bicycles could be ridden easily, they were never produced in large numbers.

In 1861, Frenchman Pierre Michaux and his brother Ernest invented a bicycle with an improved pedal mechanism. They called their bicycle a velocipede,but most people called it a “bone shaker” because of the effect of the wood and iron frame. Despite the impolite nickname, the velocipede was a hit. After a few years, the Michaux family was making hundreds of the machines annually, mostly for fun-seeking young people.

Ten years later, James Starley , an English inventor, made several innovations that revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient,and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top-heavy,and ridden mostly for entertainment.

It wasn’t until 1874 that the first truly modern bicycle appeared on the scene. Invented by another Englishman, H. J. Lawson, the safety bicycle would look familiar to today’s cyclists. The safety bicycle had equal-sized wheels, which made it easier to ride. Lawson also attached a chain to the pedals to drive the back wheel. By 1893,the safety bicycle had been further improved with air-filled rubber tires, a diamond-shaped frame, and easy braking. With the improvements provided by Lawson; bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world.
